50 blanks are delivered by the eonveyer mechder the chute to receive a blank into the pocket constituted by the then opposed niches of both of said arms. It will be noticed that the said pocket constituted by the said niches is of a width to receive one of the blank disks as therein and is open forwardly, the springfinger m being provided on the rear side of the arm I) to project forwardly and inwardly, as shown, to form a guard or retaining device against the displacement accidentally of the blank from the pocketin the conveyer and yet to constitute no substantial impediment to the expulsion of the blank from the conveyer into the receiver-pocket 2, which, as clearly indicated in the drawings, is in a plane coincident With that of the conveyer-pocket and of the swinging movement of the conveyer.

The operation will be now clearly understood, for it will be seen that the cam, acting to swing lever-arm f downwardly, will throw the lever-arm a forwardly and with it the arm I) for the greater portion of its movement; but it will be noticed that the forward end or nose of the extremity of arm Z) is in the line of the receiver Y, while the lip 13 at the extremity of arm a is to one side of the end face of said receiver, the shoulder 12 only being extended inwardly across the plane coincident with the end of the receiver. Therefore before the arm a has completed its forwardlyswinging movement the arm I) will come to an abutment against the receiver adjacent the pocket 2 thereof, when the arm a, completing its forward movement, (assuming the position relatively to the one 1) indicated in Fig. 5,) will by its shoulder 12 force the blank forwardly, rolling it along on the base-ledge 9, under the pocket, into the conveyer, and into the pocket in the receiver. The arm a having retraced its movement partially, the spring-pressed arm I) resumes its normal position relative to the one a, re-establishing the pocket, which is brought on the completion of the return swing of the conveyer under the chute-Way. The extremities of the arms a Z) have such an extent from the front to the rear or in the line of the movement of said parts as to consitute an effectual guard against the undue passage of-blanks from the chute at the time the conveyer is moving to deliver a blank. The connection between the lever-arm f and the link 0, which connects said arm with the cam-lever e, is adjustable, whereby the throw of the elbow-lever may be slightly varied, so that the shoulder 12 may be brought close to but without violent contact with the side of the receiver Y, and such connection is made by the eyebolt p, to which one end of the link 0 is pivoted, which bolt by its shank passes loosely through alug q of the lever-arm f and receives nuts 0" and 3 above and below the lug. The

adjustmentis made by loosening the one nut and turning upon the other.

hat I claim as my invention is- 1. The combination, with the chute, of a conveyer consisting of a primary member a and another member mounted thereon for a movement therewith and also for a movement independently thereof, a pocket in the top of the conveyer, the walls of which are formed by portions of the said members, a stop for limiting the extent of movement of one of said members, whereby the other member in its continued movement advances the rear wall of the pocket constituted thereby for the expulsion of the blank, and means for moving the one member into its normal or pocket-forming relation with the one carrying it on the return movement of the conveyer, and

means for imparting a forward-and-backward movement to the primary member, substantially as described.

2. In a conveyer for the purpose substantially as described, the combination, with the arm (1., adapted to move forward and back, of the arinb, mounted thereon, substantially as described, and adapted to move as one with the arm a and also to have a limited movement independently with relation thereto parallel with the plane of movement of said arm a, the arm I) being provided in its extremity with the niche S and the base-ledge 9 and thearm a having the niche constituted by the side lip 13 and rear shoulder 12, and the spring for normally maintaining both arms in their pocket, constituting relations for the purpose set forth.

3; The combination, with a conveyer consisting of the arm a and the arm I), pivoted on the side thereof, and the spring 2, and a stop k, the arm I), having in its upper end the niche 8, with the laterally-extended base 9, and the arm at, having the rear shoulder 12 and side lip 13, the spring-finger 41, applied on the arm I), substantially as described, of a receiver adapted to constitute a stop for the movement of the arm 19, substantially as de scribed.

4. The conveyer comprising the arms a and I), connected and comprising the pocket, substantially as described, combined with the angular arm f, connected to said arm a, and the cam d, and cam-lever e, the link connected to said cam-lever and having an adjustable connection with said arm f, substantially as and for the purpose set forth.
